本発明は、複数の水平管の束を支持する装置に
係わり、特に過熱蒸気発生器のボイラの水平管の
束を鉛直面内に支持する装置に係わる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for supporting a bundle of horizontal tubes, and more particularly to an apparatus for supporting a bundle of horizontal tubes of a boiler of a superheated steam generator in a vertical plane.
このような装置は、対向側に半フインを備える

め、短時間で錆やすい。 Such a device consists of a pair of vertical tubes with half fins on opposite sides. Such a device consists, by way of example, of fins having a diameter slightly larger than the diameter of the horizontal tubes to be supported and provided with holes arranged at the same pitch as the bundle of horizontal tubes. Thus, each vertical tube has a half fin fixed to the half fin of the other vertical tube via a bridge placed between the bundles of horizontal tubes, but the central part of the bridge is in contact with the hot horizontal tube. and
Since it is relatively far away from the two vertical pipes, it is difficult to cool down. Bridges formed between vertical pipes are often exposed to high temperatures in corrosive gases, so they are susceptible to rusting in a short time.
又、フインの孔部に個々に水平管を挿通するこ
とが困難なため、この装置は単一ループ式熱交換
器にしか適用できない。 Also, because it is difficult to insert horizontal tubes individually into the holes in the fins, this device can only be applied to single-loop heat exchangers.
更に、水平管の束と鉛直管との間に溶接サドル

い。 Furthermore, it has also been proposed to form a welding saddle between the bundle of horizontal tubes and the vertical tubes. Although welded saddles are placed close enough to the vertical tubes to provide adequate cooling by heat conduction, the bundle of horizontal tubes is rigidly connected to the saddles, increasing stress due to thermal expansion or vibration, resulting in , the welds are prone to cracking.

破壊されやすい。 Furthermore, it has also been proposed to form a weld flat between two adjacent parallel vertical tubes. However, this flat is too large and causes problems similar to those described with respect to perforated fins. The central part of the flat is difficult to cool due to conduction and is subject to excessively high temperatures, making it susceptible to destruction by corrosion.

大する。 On the other hand, US Pat. No. 3,267,913 consists of a pair of vertical tubes separated by a non-cutout zone and comprising half fins with a circular notch for accommodating a horizontal tube. The horizontal pipe is welded to the notch and is in contact with the vertical pipe.
Therefore, the horizontal pipe and the vertical pipe are tightly connected, and stress due to thermal expansion or vibration increases as described above.
